The idea

Being alone and being lonely are different. Being alone is a situation — and many people enjoy solitude. Loneliness is a feeling: the painful gap between the connection you have and the connection you want. You can feel lonely in a crowd, in a marriage or surrounded by colleagues.

Researchers such as John Cacioppo described loneliness as a signal, like hunger or thirst, telling us we need connection. The difficulty is that long-term loneliness can make people more wary of others — expecting rejection, reading neutral faces as unfriendly — which can make reaching out harder.

What helps is often small and repeated: regular contact with people you already know, joining something that meets regularly around a shared interest, helping others, and noticing when loneliness is shaping your thoughts about people. Reviews suggest that working on those thoughts is one of the more effective approaches.

Why it works

Loneliness is common and often hidden by shame. Understanding it as a signal rather than a personal failing makes it easier to respond to.

A real example

The situation

Nadia, a first-year student, feels lonely at university. She assumes everyone else has found their friends and nobody would want to add her.

What happened

She notices that the thought “nobody would want me” is making her avoid people. She joins the photography society, which meets every Wednesday. Seeing the same faces each week, conversations come more easily, and by term’s end she has two good friends.

The takeaway

Regular contact around a shared interest gave friendship room to grow.

Use this when you are…

• you feel disconnected, even with people around
• you have moved, changed jobs or lost a relationship
• you notice you are avoiding people

Common mistakes

• Assuming loneliness means something is wrong with you. It is a common human signal.
• Waiting for others to reach out first.
• Expecting one event to fix loneliness. Regular, repeated contact is what builds connection.

What the evidence says

Moderate evidence: Several studies support it, but the effects are smaller, the studies are fewer or less rigorous, or results vary between groups.

Loneliness is consistently linked with poorer mental and physical health. Reviews of interventions suggest that addressing unhelpful thoughts about others, and building regular social contact, tend to help more than one-off events.

Where this comes from: Social connection and health research; US Surgeon General advisories (2023).

Fields that study this: Clinical psychology, Sociology.

Try it now: One regular thing

1. List two interests you have.
2. Find one group, class or activity that meets regularly around one of them.
3. Commit to going three times before deciding if it is for you.

Questions to think about

• When do you feel most lonely, and what is usually missing?
• What thoughts about other people might be keeping you apart from them?

Take one small step toward connection today — a message, a hello, a question to a neighbour.

Afterwards, ask yourself

What did you notice after taking a small step toward connection?
